Save Our Streams

The Izaak Walton League’s Save Our Streams (SOS) program helps people just like you check water quality in local creeks and streams. Share your findings with the League, and we can get a clear picture of water quality across the country – the first step in crafting water quality solutions that work. We can also help you restore your stream to good health.

Our new video guide to identifying macroinvertebrates will help you become a bug ID expert (or at least be able to tell a dragonfly from a dobsonfly!). Includes photos and illustrations of the critters we use to measure water quality, plus identifying features and interesting tidbits. Hosted by IWLA Clean Water Program Director Leah Miller.

How do I start an SOS water quality monitoring group?
Before starting a new group, check with your local Izaak Walton League chapter, watershed association, and state and local environmental agencies to see if there is already an active group in your area. You don't want to duplicate efforts or stress out your streams from over-monitoring them. A good place to check is the Environmental Protection Agency’s Surf Your Watershed page and National Directory of Volunteer Monitoring Groups.

No local group? It's easy to start your own! All you need are a few simple pieces of equipment and a guide to stream bugs to get started.
